专业词入口Topic Entry
玻璃通孔 TGV，先把“玻璃怎么成孔、孔壁怎么金属化、两面怎么接通”拆成可验收的工艺链。For TGV, turn glass via formation, wall metallization and two-side interconnect into an acceptance-ready process chain.
玻璃通孔（TGV，Through-Glass Via）常用于射频、光电、MEMS 与玻璃中介层互连。玻璃型号、板厚、孔径与阵列、裂纹边界、孔壁覆盖、正背面图形和后段装配彼此耦合；先把截面和验收目标讲清，才方便判断可行路线与资源接口。Through-glass vias serve RF, photonics, MEMS and glass-interposer interconnects. Glass grade, thickness, geometry, crack limit, wall coverage, two-side patterning and assembly are coupled; define the cross-section and acceptance first.
先准备什么Prepare First
请提供玻璃类型与厚度、通孔直径/锥度/节距、孔数与阵列位置、正背面版图、目标导体和绝缘要求、是否允许激光或湿法路线、后续键合/贴装温度及电学或高频测试条件。Provide glass type and thickness; via diameter, taper and pitch; count and placement; both-side layouts; conductor and isolation needs; permitted laser or wet routes; assembly temperature and electrical or RF test conditions.
常见风险Common Risks
热影响或边缘微裂纹、孔径锥度和碎屑会影响后续金属化；高深宽比孔壁可能出现种子层不连续、镀层空洞或电阻离散；玻璃与金属热膨胀失配、翘曲、两面套刻和清洗残留也需提前定义边界。Thermal damage, edge microcracks, taper and debris affect metallization. Deep holes can have discontinuous seed, voids or resistance spread; CTE mismatch, warp, two-side registration and cleaning residues also need defined limits.
推荐下一步Next Step
先发玻璃截面、孔阵列版图和互连/测试指标，再拆分 TGV 工艺窗口。Send the glass cross-section, via-array layout and interconnect/test targets before defining the TGV window.
建议同时说明允许的边缘缺陷、孔径与位置公差、是否需要截面显微检查、孔壁连续性、直流电阻/绝缘或 S 参数测试，以及后段如何与芯片、载板或封装结构对接。素微 会先协助区分成孔、清洗、绝缘、金属化、双面图形和装配接口，避免只按“玻璃打孔”询价而遗漏互连风险。Also state allowed edge defects, diameter and position tolerances, cross-section inspection, wall continuity, DC resistance/isolation or S-parameter tests, and how the part joins chips, carriers or package structures. We separate via formation, cleaning, isolation, metallization, two-side patterning and assembly interfaces before matching resources.

若需在孔壁或通孔内形成铜层，先定义种子层、开口、厚度与连续性证据。For copper in via walls or holes, define seed, opening, thickness and continuity evidence.

若 TGV 是中介层或封装的一段，需与 I/O、键合和测试路径一起确认。If TGV is one segment of an interposer or package, align it with I/O, bonding and test paths.
